1. Introduction

The MMICON is a compact size man-machine interface control board with a 4*4keyboard interface , a 240*64 dots graphics LCD interface ,a RS-232C or RS-485interface , 10 isolated digital input. This control board is designed to work with PC orPLC to implement a cost-effective man machine interface.

PC based user can use it to integrate a operator interface , instead of the regularmonitor and keyboard. The MMICON has RS-232C or RS-485 ( jumper selectable ) portto communicate with PC. The PC can send out command to change the display page orsend out the string to display on the specified location. The user should need a ND-6520(RS-232C/RS-485 converter) to implement a RS-485 network .The PC can control up to256 MMICON controllers in one 2-wire RS-485 network.

PLC user can use digital I/O port to communicate with the MMI-CON. The PLC sendthe page number through digital I/O and the MMI-CON will automatically display therelated image stored in EEPROM.

When the user use OMRON PLC ,he can use RS-232C to communicate with MMI-CON port. The PLC send the page number into the PLC internal data memory (DM). TheMMI-CON polls the data memory all the time and displays the value of the internal datamemory. The DM value can be mixed with the image stored in EEPROM . The inputvalue of the 4*4 KBD can be written into the data memory. Therefore it is also suitableas a man machine interface for PLC.

The user can edit the text and paint the Images using the utility in PC environment .The hex file can be programmed into the EEPROM by regular programmer.

The MMICON is a low cost man machine interface controller. The MMICONStarter-Kit is designed to demonstrate the function of MMICON. The Starter-Kitgives three demonstrations as following:

demo 1 : 5-24V digital I/O interface(for uP, PC or PLC I/O)(240*64 LCD*256 pages)

demo 2 : PC RS232 interface(240*64 LCD*256 pages+4x4 KBD + Function_Key*8)

demo 3 : Omron PLC RS232 interface (others soon)(240*64 LCD*256 pages+4x4 KBD + Function_Key*8)


The MMICON can be applied to various application as following:

Application 1 : 5-24V digital I/O interface(for uP, PC, PLC I/O)(refer to Chap. 2)

Application 2 : PC RS232 interface àà refer to Chap. 3

Application 3 : PLC RS232 interface àà refer to Chap. 4

Application 4 : PC RS485 inteface àà refer to Chap. 5

Application 1 àà select MMICON mode 0 àà initial mode(with JP2 in INIT

position)

Application 2 àà select MMICON mode 1/2 àà (with JP2 in normal position)

Application 3 àà select MMICON mode 1 àà (with JP2 in normal position)

Application 4 àà select MMICON mode 3 àà (with JP2 in normal position)

Mode 0 : initial mode à with JP2 in INIT position Suitable for application 1

Module address = 00

Only in this mode can change to other mode

Mode 1 : PC RS232/RS485 mode à with JP2 in normal position Module address stored in MMICON internal eeprom (not LCD image EPROM)

Suitable for application 2 : PC RS232 interface(J7 in 1-2, J8 in 1-2)

Suitable for application 4 : PC RS485 interface(J7 in 2-3, J8 in 2-3)

KBD input will be stored in buffer until PC read

Mode 2 : PC RS232 mode à with JP2 in normal position Module address stored in MMICON internal eeprom (not LCD image EPROM)

Suitable for application 2 : PC RS232 interface(J7 in 1-2, and J8 in 1-2)

KBD input will return to PC immediately.

Mode 3: PLC RS232 mode à with JP2 in normal position Suitable for application 3 : PLC RS232 interface(J7 in 1-2 and J8 in 1-2)

Factory Setting :

(1) : JP2 in INIT position à mode 0

(2) : J7 in 1-2, J8 in 1-2

(3) : (if move JP2 to normal position à Mode 3)

Refer to “MMIDOS Software User Manual” for how to change operation mode.
